c The following code is compatible to Fortran and definitely can be compiled with ac F90 compiler.c This test bed program was written in Fortran an runs out of DOS (the commandc prompt). c It takes 1 second for 999900 to 1000000, and not much more for the higher ranges I c timed.c programming stategy:c 1. setup an (n by 3) matrix: cells are filled with 1's or left emptyc 2. use the algorithms to fill cells with 1's or leave empty c 3. look for voids in the appropriate areac 4. generate 40 reports to a filec The executable can be downloaded

c The main advantages I see with these algorithms are:c 1. We can do away with keeping up with the prime numbers (except for reports).c 2. These allow an incremental database, so we don't have start over as we do c now.
